Molding

Engineering resin choices are specified to minimize the erosion of structure and properties in these harsh environments with resin manufacturers’ data and feedback. Meridian helps with specific data to determine if a customer’s choice is the best suited engineering grade once all factors are considered from the Material Recommendation form.

Overmolding is a process whereby one material is molded over a second material. The initial “substrate” is commonly the harder plastic of the 2 resins. Once the “substrate” is molded, it is then placed into another mold cavity and the “over mold” resin is injected to specific surface areas of the substrate to achieve the intended design and usage.

Medical devices and components require a particularly specific production process in order to satisfy stringent medical and quality requirements. Meridian prides itself on its excellent service, production processes, quality planning and design support, and post molding capabilities to provide solutions that meet the expectations of medical industry customers and ensure that requirements in this industry are met.

Corrosion and chemical resistance is an objective in many applications exposed to various harsh environments which can cause failures in metal components over time. Engineering resin choices are available that will not cause the erosion of structure and properties. There is a shortening of product development timeframes, shorter cycle times, and lead times. The manufacturing is less complex since molding a product can be a 3-step process while metal fabrication can be 5 steps or greater.

Molding processes using bioresins that are compostable and degradable has emerged as an important “green” alternative to traditional polyurethane based plastics. Meridian is experienced in the production of plastic components molded from bioresins.
